How do you start growing shrooms from manuer?

To grow mushrooms from manure, start by obtaining fresh, high-quality manure, preferably from herbivores like horses or cows. Pasteurize the manure to eliminate harmful pathogens, then mix it with mushroom spores or a spawn that contains mycelium. Place the mixture in a suitable container or substrate, keep it in a warm, dark environment, and maintain appropriate moisture levels. After a few weeks, you should see mycelium growth, eventually leading to mushroom fruiting.
